실험 절차
To an ice-cold solution of 33.3 grams of 2-acetyl1,3-cyclohexanedione in 400 ml of methanol was added dropwise a solution of 7.2 ml of hydrazine in 50 ml of methanol and the resulting reaction mixture was heated at reflux for 20 hours. The solvent was then removed under reduced pressure and the residue was triturated in ethyl ether to give 1,5,6,7-tetrahydro-3-methyl-4H-indazol-4-one as a yellow crystalline solid melting at about 154°-157° C.
